5 exceptionally operative tips for successful OCR conversion projects

OCR
conversion services because of innumerable reasons are chosen by many
businesses from around the world. Sway of companies like IMPACT and Google has
helped to resurface the OCR methodology by advancing many useful features and
providing robust conversion facilities. There are a few tips to consider while
performing it and professional outsourcing companies are well aware of it.

Understand the
content

You
should have thorough knowledge of the material you are going to convert. It
will help you to achieve a better conversion rate even if foreign languages are
involved. Tools like Apache Tika can help you understand the language of a
document.

Don’t over
expect

There
is a caveat in every process and the same applies with converting
scanned images too. 90-95 %accuracy is more than welcomed for the services.
Even if the software and hardware are pre-configured, don’t expect cent percent
conversion rate. Also it is a costly process and the pricing can vary.
Informational and structural layout also plays a part in the information
availability.

Manage full text
to a great extent

Optical
Character Recognition processing will derive full text which offers an
excellent way to enhance digital collections. Keep an eye out for any such full
text occurances. Occurrences can be refined using keyword extraction, topic
modelling and sentiment analysis.

Careful use of
resources

Additional
language sources used by technologies like IMPACT improvise the recognition
rate by alarming margins. Historical variants and normalizations have to be
applied and sufficient technical materials must be made useful during the
process.

Post correction
techniques

Since
there may be mistakes even after OCR data conversion, a feasible way is to
adapt to post correction techniques. These vary from crowdsourcing to special
tools for data conversion professionals. Gamification offers a level of freedom and many
applaud the use of it.

Some
points to consider while planning your next project were discussed here in this
short article. These fruitful tips for OCR are not to be strictly followed as
such but can be tailor-made suiting your needs.
